Erratic Sound Performance Over Net

I like to listen to my alma mater's (UTEP) basketball games over the net. I can do so over KOFX fm in El Paso. Unfortunately, lately I cannot get the game call from the announcer whereas I do get all the .gov adds that the station announces during the game. OTOH, right now, for example, I've got KOFX blaring away with no problem. It just seems to be the game call that blanks out. The player seems to be streamtheworld.com. Big game Saturday against Tulsa for 1st place and I'd sure like to tune in.
